Detailed Pin Configuration

MIC803-44D3VM3-TR has three pins:

1. VDD: Power supply input pin.
2. GND: Ground reference pin.
3. RESET: Output pin that indicates the status of the device being monitored.

Functional Features

• Voltage monitoring: MIC803-44D3VM3-TR continuously monitors the voltage level and provides a reset signal when it falls below the specified threshold.
• Reset function: When the voltage drops below the threshold, the RESET pin is asserted, triggering a system reset.
• Timeout delay: The reset signal remains active for a specific duration (timeout delay) after the voltage rises above the threshold, ensuring stability before resuming normal operation.

Advantages and Disadvantages

Advantages

• Low power consumption makes it suitable for battery-powered devices.
• Wide operating voltage range allows compatibility with various systems.
• Small package size saves board space.
• High accuracy ensures reliable voltage monitoring.

Disadvantages

• Fixed reset threshold voltage may not be suitable for all applications.
• Limited timeout delay options may not meet the requirements of certain systems.

Working Principles

MIC803-44D3VM3-TR operates by comparing the input voltage with the preset threshold. When the voltage drops below the threshold, the internal circuitry triggers a reset signal. The reset signal remains active for the specified timeout delay after the voltage rises above the threshold, ensuring stability before normal operation resumes.
